Oil Level Gauge
Do not operate the engine for any
length of time with the crankcase oil below
the "LOW" mark on the bayonet oil level
gauge.
To check the oil level with the bayonet
gauge, unscrew and remove the gauge, wipe
it clean and insert it in the crankcase until
it rests on top of the threads. Do not screw
the gauge onto the threads. Remove the
gauge again and read the oil level.
NOTE. The gauge has readings on both
sides; one side is used if the engine has
been stopped, and the other side if the en-
gine is operating. Be sure to use the cor-
rect side.
If the engine has just been stop-
ped, allow 5 to 10 minutes for the oil to
drain down into the oil pan before taking the
reading, otherwise the reading might not
show the true amount of oil in the crankcase
and more oil than necessary might be poured
into the filler.
Engine Oil Pressure Indicator
The engine oil pressure indicator shows
pressure of the oil circulating through the
engine. Under all operating conditions the
oil pressure should hold the indicator in the
white section.
If the indicator does not
register, stop the engine at once and inspect
the oil system to find the cause of failure.
If unable to find the cause, consult your
International Industrial Power distributor or
dealer before operating the engine. ALWAYS
LOOK AT THE ENGINE OIL PRESSURE
INDICATOR IMMEDIATELY AFTER START-
ING THE ENGINE.
LUBRICATINGSYSTEM FOR THE TRANSMISSION,
PLANET POWER DRIVE, SPROCKET DRIVES, ETC.
Transmission Oil Pump
The gear type transmission oil pump
furnishes pressure lubrication to the trans-
mission gears and bearings, also to the
planet power drive.
Transmission Oil Filters
Transmission Oil Pressure Indicator
The transmission oil pressure indicator
shows the pressure of the oil circulating
through the transmission and planet power
drive. The transmission oil filters should
be cleaned when the transmission oil pres-
sure indicator hand remains in the red area
after the transmission oil is warmed to op-
erating temperature and the engine is at
full throttle and the engine clutch is engaged.
If the indicator fails to register pressure,
stop the engine and refer to your International
Industrial Power distributor or dealer before
operating the tractor.
Sprocket Drive Housings
I"
The oil in the sprocket drive housings
should be changed at least once a year.
However, do not operate the tractor more
than 960 hours without changing oil in the
sprocket drive housings.
Water Pump
The water pump is the packless type,
with a reservoir in the pump body which is
filled with chassis lubricant. Check after
every 240 hours of operation by removing
the filler and level plug, and maintain the
hiblticant level.
Clutch Compartment
When operating the tractor in water or
extremely dus.ty conditions, water or dust may
enter the engine clutch compartment through
the hole in the flywheel housing. To prevent
this, insert a 3/4 inch countersunk pipe plug.
If the pipe plug is left in, remove it after every
60 hours of operation to allow any oil accumu-
Iation to drain out.
Hydraulic System
The hydraulic system has 2 filters. The
filter on the pressure line should be serviced
after 240 hours of operation, and the filter on
the suction line should be serviced after 192.0
hours.
